Never thought much about .350 Legend.
At range yesterday, guy was shooting one, suppressed. On a Savage 111 action, and a SIG dot sight.
It was quiet, really quiet. Groups at 100 were around an inch, which with a dot sight is right good, his group was smaller than the dot. He was shooting heavy bullet subsonic ammo, of course-250 gr, maybe.
I shoot 220-250gr lead bullets loaded to 1050fps in several
300BLK rifles. Very quiet through a 30cal centerfire can. The thing that will surprise the unsuspecting is how much velocity that 220gr Lyman 311284 lead pencil retains at 300yds, and how hard it spanks steel.
It does drop more that most modern rounds making range estimation a serious requirement - a 100yd zero needs +9.4 mils at 300yds (935fps), and +20.1 mils at 500yds (878fps). All this makes for an interesting shooting session! Numbers from Strelok Pro, validated on the range from a Ruger American.

How often do you have to clean out the can from shooting lead bullets thru it??? Had someone suggest lead bullets thru my AR 300 BO with a can, not sure I want to mess with lead bullets in a AR gas system but curious about the can.

I received a free ~10” 350 barrel awhile back. Built up an opera for it and took it to the range, I think one time. It is an interesting caliber and would be fun to play with heavy subsonic loads. I am pretty sure I got die’s and some bullets as well, but don’t think I ever shot more than one box/magazine of ammo through it. I’m assuming a standard aluminum 9mm can is t strong enough to handle 350, even subsonic loads.
